Objective Accurate assessment of child oral health is important for guiding economic evaluations and informing healthcare decision‐making. Early Childhood Oral Health Impact Scale (ECOHIS‐4D) is a preference‐based instrument that measures the oral health‐related quality of life of young children. The aim of this study was to compare the utility sco...

Measuring outcomes for oral health is frequently undertaken using the decayed, missing, and filled teeth (DMFT) index. DMFT measures dental caries experience. As a condition-specific outcome, it is not relatable to consumers, nor does it capture the impact of dental caries on quality of life or outcomes that matter most to consumers. Efficient reso...

Dental caries is the most prevalent oral disease across the life course. This study modeled the population health and economic impact of a 20% sugar sweetened beverages tax (SSB) for preventing dental caries compared to no intervention (societal and healthcare perspective). A cost‐effectiveness analysis according to quintiles of area‐level socioeco...

Introduction: Accurate assessment of child oral health is important for guiding economic evaluations and informing healthcare decision-making.

Methods Data were drawn from the Multi-Instrument Comparison (MIC) survey. The EQ-5D-5L w...

The delivery of family‐centred practice (FCP) within Early Childhood Intervention Services (ECISs) for young children with a disability or development delay conceptualises that children's learning environments, parenting, family and community supports intersect to have the greatest impact on the developing child. The transdisciplinary key worker mo...

The coronavirus disease 2019 (COVID-19) has disrupted essential oral healthcare in Australia. Sources for COVID-19 transmission via dental settings is considered to have high potential due to the production of aerosols and because transmission can occur through the airborne route. However, COVID-19 cases in dentistry is reportedly low. Delayed time...
